Dont work after install

#1
After Install the BDA Driver, Win 7 says is correct, but whenstart Progdvb
Error BDA Technisat UDST7000BDA DVBS Tuner Cannot submit the tune request, device is not startet, OK
In Device List is the same error, when I try to enable.
But AC is in.
THere is 6,44 32 bit and Net Framework 3,5 on it with Updates.
Before I had XP and it works

PS.:the 64 bit version tryed to install in the x86 Folder, I canceled it, but would like to try, too
And it´s smaller as 32 bit, so I did´nt know if its right.
